A marine double D fender is a type of rubber fender used in marine applications to protect ships and other vessels from damage when they come into contact with a dock or other solid object. It is named for its shape, which is similar to the letter "D" but with two parallel sides.
The double D fender is designed to be attached to the side of a dock or pier and provides a cushioned surface for a vessel to come into contact with. The fender is typically made from a durable and flexible rubber material that can withstand repeated impacts and exposure to harsh marine environments.
The design of the double D fender allows it to be mounted vertically or horizontally depending on the specific application. It is often used in areas with high tidal fluctuations where the water level can vary significantly, and the fender needs to be able to accommodate these changes.
Overall, the marine double D fender is an important component of a dock or pier system, providing critical protection for vessels and minimizing the risk of damage to both the vessel and the structure.
These are also used in the removal industry in lighter versions to protect goods from bumps and bashing.
